  • Only install this firmware on the E5070B/71B. Do not attempt to install this firmware on a PC as this may render it unusable.


The firmware Rev. 8.01 or later can not be installed onto the analyzer, if your E5070B/71B meets all of following conditions. Please ask Keysight service center to replace the internal hard disk drive.

Known Issue for Rev. 8.11 (This has been fixed in Rev. 9.10)

  • Calculation of Z conversion (Zr and Zt) does not work properly if you set imaginary value to port impedance.
  • Absolute value measurement does not work properly if you measure absolute value using external SG control feature.

Known Issue for Rev. 6.51 (This has been fixed in Rev. 8.01)

  • Scalar mixer calibration function does not work properly. The traces is not updated after executing scalar mixer calibration.

Known Issues for Rev. 6.50 (These have been fixed in Rev. 6.51)

  • Once Ecal has been executed, part of fixture simulator function does not work properly. As a workaround, please turn off then turn on the fixture simulator (Press Analysis>Fixture Simulator>OFF then Analysis>Fixture Simulator ON).
  • Traces which are not displayed on the screen is not saved properly by the save SnP function when the port extension function is turned on. If you have to output touchstone data with port extension, please display all traces on the screen.
  • De-embedding s4p function does not work properly with other fixture simulator function, which is related with single-ended parameters. For example, when 4-port embedding is applied on port1 and port2, applying port Z conversion to port3 will cause De-embedding s4p on port1 and port2 to not work properly.

Special Notes for Rev. 3.54 and later

An initial source port control feature for transient voltage protection caused by an external DC source is added in the firmware 3.54 and later. Please refer to the "Firmware update notice and Notes when using external DC power supply" listed below when the firmware is updated.
